Choosing The Right Grinding Wheel | Modern Machine Shop
The grinding wheel is a cutting tool. It's an abrasive cutting tool. In a grinding wheel, the abrasive performs the same function as the teeth in a saw. But unlike a saw, which has teeth only on its edge, the grinding wheel has abrasive grains distributed throughout the wheel.
The abrasive grains are the cutting took of a grinding wheel. They actually cut small pieces or chips off the work as the wheel rotates. The shape of each grain is irregular with several sharp cutting edges. When these edges grow dull, the forces acting on the wheel tend to fracture the abrasive grains and produce new cutting edges. 5-5
Establishment of dynamic grinding force model for ultrasonic
Huang et al. (2019) summarized and analyzed the mechanism of ultrasonic-assisted grinding, and the results showed that ultrasonic-assisted grinding can reduce the cutting force of abrasive tools, the grinding heat, and improve the surface micro-topography. Ordinary grinding is a process that countless abrasive particles act together on the
When using vitrified or metal-bonded grinding wheels, these resistance forces lead to fracturing of the abrasive grain from the bond. In the case of organic- and resin-bonded wheels, the heat produced from the grinding interaction releases dull abrasive grains over time, exposing the new sharper grain beneath it.
How to Read a Grinding Wheel Spec - AA Abrasives
We will reference the AA Abrasives #60397 - 12x2x1-1/4 Pedestal Grinding Wheel T-1 Vitrified A36 - from our Vitrified Bonded Grinding Wheel Series. 12=Diameter x 2=Thickness x 1-1/4=Arbor Hole *Note that the arbor hole can be bushed down meaning a bushing may be inserted in the arbor hole to reduce the size of the arbor hole.
A grinding machine, often shortened to grinder, is one of power tools or machine tools used for grinding. It is a type of machining using an abrasive wheel as the cutting tool. Each grain of abrasive on the wheel's surface cuts a small chip from the workpiece via shear deformation.

The abrasive grains are blended with rubber, which cushions during grinding to produce a smoother surface texture than other bits with similar grits. Grinding Bits for Stainless Steel Bits stay cool during grinding so they won mar or discolor stainless steel.

Understanding the Marking System for Grinding Wheels
For example, 230 x 3 x 22.2mm. This represents the wheel diameter x thickness x hole size. The specification of the grinding wheel is marked as a series of letters and numbers. For example, WA 60 K 7 V. This represents the type of abrasive material, the grit size, the grade, the structure and the bond type.
abrasive grains used in making a wheel, or the size of the cutting teeth, since grinding is a true cutting operation. Grain size is denoted by a number indicating the number of meshes per
